Birds. 861 



I have observed this species flying against window-panes in the same 

 manner as the Motaeilla Yarrellii has been seen to do by several of 

 your correspondents, and will, on a future occasion, give a detailed 

 account of my observations on that subject. 



Wheatear, Saxicola (Enanthe. Nestles on heaths ; comes in April, 

 and leaves in the end of September. 



Whinchat, Saxicola rubetra. Local. Comes in April ; leaves in 

 October ; grows very fat in autumn. 



Stonechat, Saxicola rubicola. Very seldom found out of a few 

 mountainous districts. Comes in April, and leaves in September. A 

 very active little bird, which is in constant motion, and always 

 perches on the highest branches of shrubs and hedges. 



Song Thrush, Tardus musicus. Very common in March and April 

 in spring, and on its return in September and October. Nestles in 

 extensive woods. 



Blue-throated Redstart, Ruticilla cyanecula, Meyer. Comes in 

 April, leaves in September. Nestles among reeds. 



Tithys Redstart, Ruticilla Tithys. Lives in large towns, and on the 

 banks of the Ourthe and Meuse. Migrates in March and October. 

 The male utters, day and night, its melancholy note, from the summit 

 of some church-steeple or chimney-top. 



Common Redstart, Ruticilla Phcenicurus. Nestles in rocky situa- 

 tions, and is only seen in the flat country on its double passage in 

 April and September. 



Nightingale, Philomela Luscinia. Comes in the beginning of April 

 (the males a fortnight before the females), and leaves in the end of 

 September, at which time both sexes are heard to croak ; in spring 

 this sound is only uttered by the female. 



Blackcap, Sylvia atricapilla. Very common in gardens, &c; 

 comes in April, and leaves in October. Builds in hedges and shrubs. 



Greater Pettychaps, Sylvia hortensis, Penn. Common. Comes in 

 April, leaves in autumn. Its nest is generally not hidden from view 

 with much care. 



Whitethroat, Sylvia cinerea. Very common. Comes in April, 

 leaves in September. 



Lesser Whitethroat, Sylvia curruca, Lath. Scarce. Arrives in 

 April, leaves in September. A very active little bird, whose peculiar 

 cry at once discovers it to the naturalist. 



Wood-wren. Phyllopneuste sylvicola, Becht. Scarce ; migrates 

 in May and August. Builds at the foot of trees in our forests. 



Phyllopneuste rufa, Lath. Common in woods. Comes in March, 

 leaves in October. It has a melancholy two-noted cry.
